SEWING-MACHINE 'I 'READLEQ SPECIFICATION forming part 'of Letters Patent No. 261,446, dated July I8, 1882. Application filed June'19, 1882. (No model.)

To all whom it may concern I Be it known that I, WILLI IM L. GROUT, of

Orange, county of Franklin, State of Massachusetts, have invented an Improvement in Sewing-Machine Treadles, of which the following description, in connection with the accompanying drawing, is a specification.

My invention has for its object a novel construction of the treadle to support the crank of the driving-wheel at each end.

In this my invention I have mounted the adjustable bearing-screws in a brace which connects together the side pieces of the treadle, thus making a very firm support for the crankshaftand bracing the table very firmly.

The drawing represents in front elevation at sewing-machine table embodying my invention.

1n the drawing, A represents the side pieces of the treadle, and B the brace connecting the said side pieees,the screws 0 and rod 01 uniting the said side pieces and brace, the rod (1 also supporting the treadle e, connected by link f with the crank of the crank-shaft G,

pointed or made conical at its ends and supported by the bearing-screws h i, having conical recesses at their inner ends and made adjustable in the upright bearin g-bars b b of the brace B, the said brace being as usual, with the. exception of the addition ot' the said bearcrank-shaft G. The head of the bearing-screw 'i is exposed through a hole left for that purpose in the side piece, so that the said screw may be readilyadjusted by means of a set- 35 screw. Outward bending of the bar 12 is obviated by the side frame against which it rests. The link f passes back of the curved part b of the frame, and acts to prevent the dress of the operator coming against the link and wheel m. 4.0

The addition to the usual brace, G, of the two bearing-bars enables me in a very cheap and simple manner to support the driving-wheel at both ends of its crank-shaft andin adjustable bearings, which enables the crank-shaft to be held steadily and to be run with the minimum of friction, and enables wear in the hearings to be compensated for.

I claim The side pieces, A, the brace B, provided with the bearing-bars and the adjustable bearing-screws, combined with the crank-shaft supported at each end in the said bearing-screws, and the balance-wheel thereon, as shown and described.

In testimony whereof I have signed my name to this specification in the presence of two sub-
